Intelligence agents from the US, Britain, and Israel are helping Kenya investigate the Islamist militant attack on the Westgate Shopping Mall in Nairobi, a building that newly released video shows has been gutted in the senseless violence.

The death toll is at least 72 lives lost, and it is feared there are scores more bodies beneath the rubble.  The video from Kenya’s NTV shows the rooftop car park collapsed in through the top two floors.  Some fear that hundreds might have been trapped in the grocery store when the walls caved in.  One morgue in Nairobi is reportedly preparing to receive as many as 160 new corpses.

Of the eleven suspects reportedly in custody, ten of them might have been picked up at Jomo Kenyatta International Airport in Nairobi, trying to leave the country.  One of them reportedly is a 35-year old Briton of Somali origin who drew attention to himself because of his bruised face, dark glasses, and travel papers that didn’t show he had entered Kenya legally to begin with.

Germany, Canada and Interpol are also contributing to the investigation.
